In June, the Loya Jirga, or grand council, elects U.S.-backed Hamid Karzai as interim leader. Karzai chooses the members of his government who will serve until 2004, when the government is required to organize elections.

Amid increased violence, NATO takes over security in Kabul in August. The effort is the security organization's first-ever commitment outside of Europe.

The Loya Jirga adopts a new constitution following input from nearly 500,000 Afghans, some of whom participate in public meetings in villages. The new constitution calls for a president and two vice presidents, but the office of prime minister is removed at the last minute. The official languages, according to the constitution, are Pashto and Dari. Also, the new constitution calls for equality for women.

Presidential elections are held. More than 10.5 million Afghans register to vote and choose among 18 presidential candidates, including interim leader Karzai. Karzai is elected with 55 percent of the vote.

The nation holds its first parliamentary elections in more than 30 years. The peaceful vote leads to the parliament's first meeting in December.

Amid continuing fighting between Taliban and al-Qaida fighters and the Afghan government forces, NATO expands its peacekeeping operation to the southern portion of the country. After the forces take over from American-led troops, Taliban fighters launch a bloody wave of suicide attacks and raids against the international troops.

The Afghan government and NATO confirm that Taliban commander Mullah Dadullah was killed during a U.S.-led operation in southern Afghanistan.

The international community pledges more than $15 billion in aid to Afghanistan at a donors' conference in Paris, while Afghan President Hamid Karzai promises to fight corruption in the government.

President Barack Obama names Richard Holbrooke as a special envoy to Afghanistan and Pakistan. Mr. Obama announces a new strategy for the Afghanistan war that would dispatch more military and civilian trainers to the country, in addition to the 17,000 more combat troops he previously ordered. The strategy also includes assistance to Pakistan in its fight against militants.
